It worked great.
I used the silicone caulk to glue my three cubes, that I bought at Petco together. Now I don't have to restack them every time I change my water. Sorry, not a great picture.

Good price for quantity - is enough to completely seal a 55 gallon tank
Is a quality silicone but read the instructions wrong thinking it had a 24 hour dry but is only 24 hour cure, and has a 7-14 day dry time, which is inconvenient. It has a strong smell which takes breath away and burns your eyes when applied so use in well ventilated area. A sealant tool did not work, you have to use your fingers to smooth the seems, and only have seconds to smooth out. Seal one seam at a time because of the very short set up time and will not be able to go back and smooth the sealant. Applied a masking tape but you must immediately remove the tape, or it will damage the seem causing to remove and reapply, if removing after minutes. Keep the screw on tip installed if you don’t use entire tube. Resealed several aquariums and canister filters. Plus - Did use this sealant for greenhouse polycarbonate panels ILO the clips holds and seals. Allows for easy replacement years later versus the calking (very difficult) and foam which is unsightly.

The Seal that lasts
Took an aquarium from 1992 from my childhood and with some care and work brought it back to life for my sons to enjoy. It takes 7 days to dry, and clean the old stuff off religiously, don’t mess around get every spec of it off and when you think your done do it again. Apply this product and it will work. Not a drop … not a nasty yellow color good value, applies good. Vent the room it will stink while it drys

Safe for aquariums
I am pleased with the end result. I tape off my corner seams for crisp lines visible when set up. I raise Discus fish. I can't tell the difference between this and clear silicone off the shelf but decided not to risk it and chose this one. True silicone sealant is messy so have disposable rags handy.

Completely worth it!
This went on smooth and evenly. The smell was horrendous, in addition to having the vent on, my husband used a face mask with a filter on it to help keep out the noxious fumes. We now have it in the bathroom but it stank up our downstairs for a few hours. He taped the edges to make sure he got a nice straight edge, if you do so, be sure to take the tape off before it starts to dry! I set a timer for him for 8 minutes, you have 10 minutes before it starts to set. Unlike the tube kind, this gives you a nice, even spread with no sudden lumps. We've used both and you can tell which one we used on each tank. There is also something to be said about peace of mind knowing this sealant is safe for aquariums. There is no wondering and hoping I didn't just put something in the tank that will kill off all of the fish. Well worth the money and highly recommended.

Very strong material. Does the job. Wear a face mask, use a fan or be outside. The odor is very, very strong.
